Abstract

This article proposes an interpretation of the use of the lemma ὁ κανὼν τὴς ἀληϑείας – regula veritatis in Irenaeus’ Adversus haereses. It is commonly interpreted as a compendium of the main items of Christian faith or as indicating the wholeness of the faith. These interpretations focuse themselves in terms of the “contents” of faith. We propose to understand it in a more formal way, as a lemma that indicates the formal structure of Christian truth, the specific shape that keeps the objects of faith joined together.
